help meeeeeeeeeeeeeeeeeeeeeef(x) = 2x - 7. evaluate f(0.5)

Answers

Answer 1

Answer:

f(x)=-6

Step-by-step explanation:

f(0.5) means that x=0.5, so you substitute the x with .5 and multiply it times 2 which will get you 1. Then you subtract 7 to get -6.

Answer 2

Answer:

f(0.5)=-6

Step-by-step explanation:

f(x)=2x-7    f(0.5)

Just put in 0.5 for the x.

f(x)=2(0.5)-7

f(x)= 1 - 7

f(0.5) = -6

I hope you understand how to do these

Hope this helped :)

These are consecutive interior angles so they equal 180.
7x+35+84 = 180
7x+35 = 96
7x = 61

X = 8.714285714285714

Answer:

x=7

Step-by-step explanation:

since the two angles are equal, set them equal to each other and solve for x

7x+35=84

subtract 35 from both sides

7x=49

divide both sides by 7 to isolate x

x=7

i’ll try to break it down for u so u can understand a little better.

the horizontal line is X and the vertical line is Y.

if u start in the middle going horizontally to the right u can find X and X will = 2

to find Y u need to start in the middle and count upwards until you find where the lines meet to create a point. Y = 1

X/Y = 2/1 which can simplify to 2

But since the line is going from left to right and going downwards it is negative hope this helped :)

An inequality is a statement that compares two expressions that are strictly equal.
True or false

Answers

Answer:

False

Step-by-step explanation:

an inequality is a relation which makes a non-equal comparison between two numbers or other mathematical expressions.

Answer:

False.

Step-by-step explanation:

In truth, an inequality is a statement marked by any of these signs:

< less than

> greater than

[tex]\leq[/tex] less than or equal to

[tex]\geq[/tex] greater than or equal to

For example, if I wrote x < y. This means that x must always be less than y. Now, if I wrote c [tex]\geq[/tex] d, this means that c can be greater than OR equal to d. If you see a line under one of these signs, it means (sign) or equal to. So at times, they can be equal, but not strictly. That would be an equation.

Explanation:

If A < B, then 1/A > 1/B. Applying the reciprocal flips the inequality sign.

For example, if 2 < 3, then 1/2 > 1/3. It might help to look at the decimal representations

1/2 = 0.500

1/3 = 0.333

We see that 1/2 is larger.

How will you know that the expression is a perfect square trinomial?

Answers

Answer:

An expression will be said to be a perfect square trinomial if it takes the form of ax² + bx + c and if it satisfies the condition b² = 4ac.

Step-by-step explanation:

An expression which is obtained from the square of a binomial equation is known as perfect square trinomial.

Now, the conditions for which an equation will be called a perfect square trinomial are;

i) It is of the form: ax² + bx + c

I) It satisfies the condition: b² = 4ac.

Thus, the perfect square formula could take the following forms:

(ax)² + 2abx + b² = (ax + b)²

Or

(ax)² − 2abx + b² = (ax − b)²

Suppose a basketball player has made 291 out of 389 free throws. If the player makes the next 2 free throws, I will pay you $38. Otherwise you pay me $50. Step 1 of 2 : Find the expected value of the proposition. Round your answer to two decimal places. Losses must be expressed as negative values.

Answers

Answer:

The expected value of the proposition is -$0.76.

Step-by-step explanation:

It is provided that a basketball player has made 291 out of 389 free throws.

Then rate of him making a free throw is,

[tex]P(\text{free throw})=\frac{291}{389}=0.7481[/tex]

The probability that he makes the next 2 free throws is:

[tex]P(\text{Next 2 free throws})=(0.7481)^{2}=0.5596[/tex]

The payout rules are:

If the player makes the next 2 free throws, I will pay you $38. Otherwise you pay me $50.

Compute the expected value of the proposition as follows:

Expected value = $38 × P (Makes both) + (-$50) × P (Misses both)

                          [tex]=($38\times 0.5596)+(-$50\times (1-0.5596))\\=21.2648-22.02\\=-0.7552\\\approx -$0.76[/tex]

Thus, the expected value of the proposition is -$0.76.
